OpenVSP 3.45.3 Released

Posted on by

Mostly a bugfix release, but with a couple small features for good measure.

Version 3.45.X is going well. All new features are going into it and fixes will not be back ported to 3.44.X after 3.46.0 is released. The big change in 3.45 is the update to VSPAERO. The only reason you should stick with 3.44.X is if you are a production user of VSPAERO who can not update their processes to 3.45.X at this time. If that describes you, you should be excited about 3.45.X and eager to upgrade as soon as possible. So, you should really be testing it now and updating your processes to the new version.

There are some new options for interacting with the 3D window.

Press ‘n’ (or choose ‘View Normal To’ from the menu), pick a point, and the 3D view will be centered at the selected point, your view will be aligned with the local normal vector, and the center of rotation will be set to the selected point.

Press ‘z’ while rotating, and instead of rotating the 3D trackball, you will only rotate about the camera Z direction. Use this when you like your 3D view direction, but not its orientation on screen.

Press ‘x’ ( or choose ‘View Front Of’ from the menu) with a Geom selected, and the view will be centered on and aligned with the X direction of that Geom.

There are a handful of fixes for VSPAERO including a fix for bookeeping of group forces/moments and adjustments to the cutoff value that will help with models of broadly different scale.

3D backgrounds now work with photos and filled images (not just line drawings anymore).

Two bugs were found when looking at the FEAMesh mass calculation. The cross sectional area for beam elements was not being calculated. Instead, the default value was used. The conversion factor for g/cm^3 was 3 orders larger than kg/m^3 instead of 3 orders smaller. And people think metric is easier…

RoutingGeom would crash because it doesn’t really have surfaces.

Calling UpdateGUI() from the API when the GUI is not running should no longer cause a hang.

Features:

  • View Normal To
  • Camera Z rotation
  • View Front Of

VSPAERO Updates:

  • Fix book keeping of group forces / moments
  • Modified cutoff value for models of different scale
  • Fixes for python optimization API

Bug Fixes:

  • Fix formatting of Cull Orphans Slider
  • 3D backgrounds with filled images
  • FEA Beam properties (including area) were not calculated, fixes mass
  • g/cm^3 conversion factor fixed. Fixes FEA mass calculation.
  • RoutingGeom crash due to no surfaces fixed.
  • API UpdateGUI() hang when GUI not running fixed.
